Wang Cai never expected things to resolve so smoothly. The Heart of Ferocious Beast, which felt like a mere stone in his hand, was so actively cooperating with him. All he had to do was to integrate his Spiritual Energy Avatar into the first layer of the Reincarnation Pearl.
The Spiritual Energy Avatar originally contained a trace of the soul origin, but now this trace had grown strong enough to become a soul of its own.
"What’s your name?" Mu Can asked.
Different from Wang Cai, Mu Can was far more interested in the Demon Ancestor himself than the Heart of Ferocious Beast.
"My name is Demon Ancestor Yin Tian," the avatar replied. Having received Wang Cai’s promise, the avatar had completely opened up to trust and was fully prepared to cooperate with Wang Cai.
"No, the Demon Ancestor is called Yin Tian, but you are now an independent entity and should have your own name."
After understanding the avatar’s experiences, Mu Can felt a twinge of compassion for it. As a person, being trapped inside a heart for so long was a torture indeed.
"I don’t have a name," the avatar said, then fell silent.
"How about you give me a name?" the avatar suggested after a moment, regaining its spirit.
Mu Can thought for a moment and said, "Although you aren’t the Demon Ancestor, you originate from the same source, so let’s call you Yin Fan, with the hope that you can live well in the Mortal World."
"I have a name now, haha, I have a name!" The avatar, Yin Fan, had its own name and became a new individual.
If the Demon Ancestor from the Demon World found out that the Spiritual Energy Avatar he’d whimsically created now had its own name, it’s uncertain whether he would laugh or remain silent.
"Woof! Yin Fan, I will extract all the life force from within the heart. Once the life force is completely drained, the confinement power of the Heart of Ferocious Beast will be at its weakest. You must seize the opportunity to break free," Wang Cai said solemnly to Yin Fan.
To make Yin Fan trust him, Wang Cai even swore a poisonous oath in the name of the Heavenly Dao.
Such oaths, if broken, would incur direct punishment from the will of the plane, which is why promises made in the name of the Heavenly Dao are considered credible. This is also why Yin Fan trusted Wang Cai.
"Got it, don’t worry," Yin Fan indicated it understood.
Although Wang Cai was the Artifact Spirit of the Reincarnation Pearl, he still preferred to appear in the form of a big black dog.
With Yin Fan’s cooperation, the process that followed went much smoother.
A vast amount of life energy was drawn out from within the heart, which gradually started to atrophy from its previously restored smoothness.
As the life energy was extracted, it merged into the surrounding environment.
Originally, the place where Mu Can and Wang Cai were situated was just a small dark room, where even Mu Can’s vision could not see beyond ten meters.
But as the dense life energy merged, the surrounding space gradually grew larger. Mu Can saw that their location was on a stone platform about three meters square. As the space expanded, their field of vision became clearer, and they saw that the platform was surrounded by sand—it turned out to be a vast desert.
"Where is this? Why is it a desert?" The first layer of the Reincarnation Pearl was a vast space filled with rich soul energy, the second layer was a tiny plane space saved by a Heavenly Dao person, the third layer was a Library capable of adjusting the speed of time, but the fourth layer was just a desert with nothing but sand. This was completely out of Mu Can’s expectation—as he had imagined, the fourth layer of the Reincarnation Pearl should be a place not much different from the previous three.
"What do you know, this is an Interface Seed," Wang Cai looked at Mu Can with a gaze that you might give to a country bumpkin.
Mu Can stared at Wang Cai without saying a word but gritted his teeth. Wang Cai quickly tightened up and hurriedly began explaining to him.
"Though it’s only a Silver Level Interface Seed, its rarity is enough for the big shots of the Supreme Interface to fight over."
This was the first time Mu Can had heard of Interface Seeds. The Three Realms were originally just a broken plane that couldn’t even compare to a Silver Seed, so the matter was normal.
"In the Supreme Realm, merging with an Interface Seed requires immense chance. My old master also obtained such a seed by a fluke. You should know, such an Interface Seed can grow to rival the Three Realms you currently reside in," Wang Cai looked at Mu Can with an air of smugness.
Whenever Wang Cai had the opportunity to educate Mu Can, he would act . Mu Can was already used to it.
"It’s almost time. Get ready, Yin Fan." Seeing that most of the life energy had been drawn from the Heart of Ferocious Beast, Wang Cai quickly spoke out to remind him.
"Alright, I’m ready." As the life energy was extracted, Yin Fan could feel the power binding him weakening. Although his own strength was also dwindling, his desire for freedom meant he could not worry about that anymore.
"Woof! Now is the time."
The sound, like a bubble bursting, was so jarring in the silent space. A pale blue silhouette instantly broke free from the binding of the Heart of Ferocious Beast and slowly stood to one side.
"Dog Demon Technique, Seal!" As soon as Yin Fan was freed, Wang Cai launched another sealing, confining the Heart of Ferocious Beast.
"Hehe, got it." The Heart of Ferocious Beast, deprived of life energy, slowly shrank and eventually became the size of a bead, which Wang Cai grasped in his hand and tossed lightly to Mu Can.
Mu Can caught the bead clumsily and asked, "Is this still of any use?"
"Ignorance. Even though the life energy has been drawn out from the Heart of Ferocious Beast, the massive slaughter energy is still present. Hehe, what you’re holding now is a mighty weapon indeed."
"Eh? Isn’t that very dangerous?" Mu Can’s hand shook, almost unable to hold it steady.
"Don’t worry, my Sealing Technique is quite reliable. Without the correct unscrewing gesture, you could throw it away now, and nothing would happen."
After speaking, Wang Cai passed on the activation gesture for the Heart of Fierce Beast to Mu Can.
"Thank you!" Mu Can put away the Heart of Ferocious Beast seriously and thanked Wang Cai, a rare gesture from him.
"Hehe, there’s no need for thanks between the two of us," Wang Cai was somewhat embarrassed and quickly said.
Mu Can knew that, with the massive amount of Slaughter Energy contained within the Reincarnation Pearl, if used properly, its power could undoubtedly be as great as having a million soldiers of the Demon Clan.
The freshly liberated Yin Fan spoke, being able to reclaim a human mindset instead of being confined within the tiny heart, Yin Fan’s mood was clearly very good.
